Automakers generally know a lot more about their engines and how they are
manufactured than the people who work in repair shops or write magazine
articles and blogs, so IMO, the safest thing to do is to follow the
automaker's break-in recommendations. I'm not sure about other
automakers,
Toyota runs new engines to redline for a while after they are assembled,
and
then again on a chassis dyno as the cars are coming off of the assembly
line.
I don't necessarily follow what I preach, and when got in the 200 ~ 300
new
cars I've driven, I just drove them the way I expected to use that
particular car, and experienced no engine problems.
